ATOMIZER.

Specification of Letters Patent.

Patented May 18, 1920.

Application filed December 2, 1918. Serial No. 265,043.

To all whom it may concern:

Be it known that I, JOHN H. BEYNON, a citizen of the United States,residing at Ontario, in the county of San Bernardino and State ofCalifornia, have invented new and useful Improvements in Atomizers, ofwhich the following is a specification.

This invention relates to improvements in atomizers.

One of the objects of thisinvention is to provide an atomizer in whichthe delivery tube may remain open but from which the liquid iseffectively trapped against leakage irrespective of the position inwhich the atomizer may be placed or located by hand, and irrespective ofthe position which the atomizer may assume, accidentally or otherwise,in a traveling grip, the perfection of this feature being accomplishedin the entire absence of stoppers and valves.

A further object of my invention is to provide an atomizer in which theonly opening exterior thereto is provided by the delivery tube andwherein the reservoir is filled through said tube, all egress throughsaid tube excepting the atomized spray being completely trapped.

A further object is to provide a trap chamber in surrounding relationwith respect to the delivery tube, the latter having trap portion,preferably perforated, through which drippings or other liquid whichmight have gained access to said tube will not only be trapped againstdischarge therethrough, but will be delivered to said chamber.

My invention also includes a novel form of partition adapted to coactwith the reservoir whereby the liquid therein will be held againstescape into said trap chamber in any un-atomizing or inoperativeposition in which the device might be disposed.

A further object of my invention is to dispose the air and liquid tubesin a novel relation with respect to the reservoir and the delivery tube,and in such relation with re spect to the partition as to prevent theliquid from accidentally escaping or leaking through the liquid tube,from the reservoir and out through the delivery tube, notwithstandingthe fact that the delivery tube is in normally open communication withthe reservoir through said liquid tube.

My invention has many otherobjects and features which will be more fullydescribed in connection with the accompanying drawing, and which will bemore particularly pointed out and ascertained in and by the appendedclaims.

In the drawing Figure 1, is a longitudinal vertical sectional view of anatomizer embodying the preferred form of my invention.

Fig. 2, is a similar View showing the atomizer in an upright oroperative position.

Fig. 3, is a similar view showing the atomizer in an inverted position,these three po sitions illustrating the manner in which the liquid isretained in the reservoir.

Fig. 1, is a sectional viewon line 4.4 of Fig. 1.

Fig. 5, is an enlarged sectional view of the base end of the atomizershowing the manner in which the free end of the distributer tube issupportedly mounted.

Like characters of reference designate similar parts throughout thedifferent figures of the drawing.

As illustrated, 1 designates a unitary body in which the device of myinvention is incorporated and which may be formed of glass or any otheravailable material. This body is provided with a reservoir 2, of a crosssection and length capable of containing a predetermined maximumquantity of liquid, which will be prescribed in theform of instruction,or indications on the atomizer, so that the liquid level will besubstantially below the longitudinal axis of the reservoir when thelatter is in a horizontal position. At its base or bulb end, thereservoir is provided with a flanged opening 3, to facilitate insertionof an air tube 4:. A cork or other form of tiller 5, surrounds the freeend of a distributor tube 18, herein-after described, to support thesame. A ferrule 6 may be fitted over the flange of said opening 3, and Icement or otherwise anchor the free end of the distributer tube 18, tosaid ferrule 6, as indicated at 6. This also makes a leak proofconnection between the open end of the tube 18 and the ferrule 6.

The air tube 41, is bulbed at 7, to spread the nipple S, of a hand bulb9, of the usual type, which constitutes the means for forcing airthrough said tube 4;. It will be noted that the bulb 9 is not greater indiameter than the maximum diameter of any other part of the atomizer,therefore, the device of my invention is capable of being inserted. intoa cylindrical container, as indicated in dotted lines, without requiringany off-set compartments and of cross section only slightly greater thanthe greatest cross section of the atomizer and uniform throughout itslength.

The reservoir has a cupped base wall 10 which serves to stiffen thebody, and from this base wall, the annular wall 11, which is shownoctagonal, tapers toward the front of the atomizing body to a point ofmaximum convergence 12, from which it flares toward its juncture at 13with the periph ery of greatest diameter of a trap chamber Thus it willbe seen that the trap chamber 1% and the reservoir 2, are in contiguous,integral and end to end relation. From its maximum diameter, said trapchamber 14 tapers toward its juncture with a delivery tube 15, at 16.llearwardly from its uncture with the reservoir 2, the chamber 14 tapersat 17 and is elongated to form a partition which is shown tubular inshape, as indicated at 18. This tubular partition 18 is axially disposedwith respect to the reservoir 2, and has openings 19, thereto, near thebase thereof. It will be noted by reference to Fig. 1, that even in ahorizontal position of the atomizer, the partition tube 18 isinaccessible for discharge of liquid therethrough, and when the atomizeris inverted, as shown in Fig. 3, the liquid seeks a position fartherremote from the intake openings 19, of said tube. In this latterposition, the juncture of the reservoir 2 with he chamber 1%, forms thebottom which supports the liquid which is housed between the tube 18 andthe wall of the reservoir. Only in ase of a longitudinal joltingmovement in the horizontal position shown in Fig. 1, could the liquidenter the partition tube 18, and then, what liquid did find ingressthereto, would, the atomizer were inverted, merely flow into and betrapped by chanio-er 11-. If the atomizer were again righted, the wall17, which gently merges into the partition tube 13, would guide theliquid into ti o latter from which it would discharge into the reservoir2.

Thus it will be c that with this novel combination of rese voir -i itionand trap chamber the liquid will, under anything like normal conditions,be confined in the reservoir where it belongs, but that even if itshould reach the trap chamber, it will be promptly returned to thereservoir whenever the atomizer is righted.

Reverting to the delivery tube 15, its dis" charge end 20 is exteriorlydisposed with respect to the trap chamber 14c, and it eX- tends inwardlythereof and in axial relation thereto wherel that portion of the tubeinterior to said chamber will be in such ample spaced relation theretoas to effectively prevent any liquid in said chamliier -from egressingoutwardly through said tube or even entering said tube Whereas,

any dripping resulting from the atomizing action, and which remained insaid delivery tube, would be returned to said chamber 14. It will benoted that the delivery tube 15 is in alined relation with the partitiontube 18, and is therefore in open communication with the reservoirthrough said tube 18. One of the reasons for this specific dispositionof the deliv ry tube 15, is to facilitate discharge of the atomizingtubes into said delivery tube 15, and a further reason is to permit theintake end 21, of the delivery tube to house the atomizing ends of theliquid and air tubes, as will presently appear.

A further and distinct teatin'e of my invention is to provide thedelivery tube 15 with a trap, and in the preferred form, this trap isperforated in a manner to deliver to the trap chamber 1 rif the atomizeris in other than an operative or upright position.

Between its ends, and inside of the chamber 14, the tube 1.5 is flaredat 22, in annular formation outwardly from its prevailing cross section.This alone, would serve to catch any liquid that entered the tube 15 butit would retain it until the atomizer was righted. Therefore, in Orderto provide for constant drainage of this trap, I provide the same with aseries of annular perforations 23. These holes 23 are not located in thediametri r-al crest of the flare of this trap, but somewhatrearwardlythereof with respect to the direction of flow of the atomizedliquid. Thus, instead of vitiatinn' the force of the air blast from theair tube by permitting leakage into the trap chamber, the holes open tothe tube 15 rearwardly with respect to the direction of the blast andmerely serve to permit of entrained streams of air to be induced throughsaid holes 23, as result of the air stream from tube 4. If the holeswere in a facing position to the a proaching blast from tube 4:, aportion of the force of such blast would be lost through said holes.Thus I am enabled to provide a drainage trap in the delivery tubewithout reducing the forte of the air blast therethrough.

A liquid tube 2% is advisedly connected in supported relation with theair tube l, alongside of which it extends, and this connection may beeffected by cement or any other suitable expedient. This liquid tube211: has it." intake end disposed in open communication with thereservoir 2, near the base thereof, so that it will be in receivlugrelation to the liquid therein at all times when a sufiicient supply ispresent, and when the atomizer in an upright position. The discharge endof the liquid tube curved into atom... .ing relation with the dischargeend 27 of the air tube. The liquid tube is provided with a bore of uni-'such an extent as to restrict the flow therethrough under induction ofthe air stream from tube 4:.

it. further feature is to extend the discharge ends of tubes 2% and 4:into the intake end of the delivery tube in such a manner that thelatter will house the same as regards their atomizing action. Because ofthe body of air in the trap chamber which will normally be quiescent, amore responsive atomizing action as a result of operation of the bulb 9,can be had by protecting the atomizing spray with the delivery tube andconfining it therein. Ofcourse, the air in chamber let will be set inmotion as a result of the atomizing action but it will not inter fore asan abutment in front of the discharge ends of tubes 2a and at. Ratherwill it sup ply entrained flows of air not only through holes 23 butthrough end 21, replenishment of air to chamber 1-:lbeing effectedduring intervals between contractions of bulb 9. Thus practically thefull. force and effect of the blast from tube a will be available notonly to induce a flow through liquid tube 24, but to also force theatomized particles outwardly through the delivery tube. lVhile I haveshown the discharge end of the delivery tube shaped especially for nasaluse, it will be obvious that the contour can be varied at will to meetthe require ments of throat use.

Now it will be seen that one of the great advantagesof' my atomizer isthat all parts thereof are concentric from a common longitudinal axis,there being no 'parts eccentric or off-set from such axis, therefore,the atomizer can be laid down on a dresser in any position and it iscapable of being placed in a container of uniform cross sec tion with abore only so slightly in excess of the diameter of the largest part ofthe atomizer as to permit the latter to be freely ii'iscrted therein Atraveler can place this atomizer in a grip or traveling bag without fearof leakage, either with or without a container, and I avoid the cost ofvalves such as now are used to prevent leakage and whichfrequentlybecome turned into an open position as a result of the jarsand jolts incident to carrying an atomizer in a traveling bag.

It will be seen that the novel mounting of the free end of the partitiontube in the cork stopper, and by its anchorage with the ferrule, hatwhat would otherwise make the juncture at 13, a point of weakness, iswholly avoided. A cork ring 5' may be employed to properly support theair tube a, in place in the partition tube 18. It will be understoodthat when the parts are once as sembled, it will never be necessary tore move the various tubes from the body 1.

The bulb 9, will be readily removable for the purpose of sterilizing thebody 1. There fore, the cork rings and the ferrule are not to beconsidered in the light of removable stoppers.

In order to inform the user as to the pre determined maximum quantity ofliquid beyond which the reservoir; should not be charged, the base ofthe reservoir, if of glass, may be ground, colored or otherwisedifferentiated from the remainder of the reservoir so that when theliquid reaches the line of demarcation, in filling the atomizer, theuser will know that fact when the liquid becomes visible above suchline. lVhile it is desirable and advantageous not to over charge thereservoir, still, such over charge if not extreme, would not cause theatomizer to leak out through the delivery tube since the trap chamberlet would always catch the over-flow. However, in an atomizer, as in allother devices, certain limitations are controlling in its most eflicientoperation and use, and the public soon learns the advantages offollowing instructions.

It is believed that the advantages and utility of my invention will befully understood from the foregoing description, and while I have hereinshown and described one specific form of my invention, I do not wish tobe limited thereto except for such limitations as the claims may import.
